Telecom Routing Administration
The industry recognized source for routing and rating data
This page is intended to note items of pertinent interest that may be occurring with TRA data and with industry activity that may impact TRA data. Links to other sites may exist. Items will be added top to bottom. Retention length of items may vary. Information on this page will be updated as may be needed - this should not be considered a daily or weekly news page. Countless activities are occurring in the telecommunications industry daily and cannot all be listed here. Comments are appreciated. Two sections to this page exist:
Based on information provided to TRA on or before the database update date identified below, the following NPA (Area Code) split details (NPA NXXs) have been entered in the TRA databases via mass updates and will be reflected in the next issue of TRA products following these dates (the specific product dates for the monthly LERG and TPM are listed). The NNAG dates are the same as the LERG. Please note, for various reasons, split details are subject to change before and during the permissive dialing period (extent of changes will vary). Also listed on this table may be cases where a split has been identified via a NANPA PL to be forthcoming, but for which data has not yet been provided to TRA or entered into TRA databases. Splits that may have been announced but subsequently were suspended by the regulatory body having jurisdiction, are not listed.
This table represents geographic splits only, not overlays. Where splits may have multiple end dates for permissive dialing (e.g. for wireless), the primary (usually wireline) date is listed. Information will be retained on this table for a short time past the start date of the permissive dialing period of each split. Splits are listed in order of the start date of permissive dialing.
Note: No NPA splits have been scheduled since the last occurred in 2008. NPA relief activity is now addressed via overlays. However, splits versus overlay as a means to address NAP relief is the purview of state regulators in the United States and of national regulators in other NANP countries. If a decision is made to address a given situation with an NPA split, the following table will reflect it.

NANPA Planning Letters
Often related to Area Code activity, for your reference, the following Planning Letters (PLs), issued by the North American Numbering Plan Administration were placed at the NANPA web site www.nanpa.com during the last completed calendar month. They are noted here to keep you abreast of any new information. However, check the NANPA site for the listing and availability of any past or late-breaking PLs. In addition to NANPA PLs and News Releases regarding Area Code activity, Local Service Provider sites and Public Utility Commission sites often contain split related information. Commission sites can be reached by linking through www.naruc.org. The extent and timeliness of information may vary by site.
|PL-474||NPA 854 to Overlay NPA 843 (South Carolina)|
|PL-473||NPA 825 to Overlay NPAs 403/587/780 (Alberta Canada)|
|PL-472||NPA 548 to Overlay NPA 226/519 (Southwestern Ontario, Canada))|
- Effective September 22, 2014, the GUI (graphical user interface) associated with input to the underlying database for the vast majority of TRA products was overhauled to address direct input into the database. The database itself has been generating output products since 2103. The GUI migration was the last but most complicated component of the overall migration to a more robust and addressable operating environment which will permit added features and quicker turnaround for changes to the database and when applicable, to products. Due to the migration effort, changes to various products (e.g. LERG), relative to industry modification requests, have been held in abeyance, but are expected to resume in 2015.
- Effective February 2013, the Telcordia Routing Administration has been renamed the
Telecom Routing Administration. This aligns with it now being an organization within
iconectiv. iconectiv is a fully owned subsidiary of Ericsson. The Telcordia
Technologies, Inc. purchase by Ericsson was completed in early 2012. Many of the
then Telcordia organizations and products were incorporated into Ericsson. Several,
primarily those involving intercarrier interconnection, were placed into iconectiv.
